Steel 1112-ANN vs 1112 CD-SR
Steel · 1112 temper comparison
1112-ANN and 1112 CD-SR are two conditions of the same steel grade, 1112: ANN (annealed) versus CD-SR (cold drawn, stress relieved). The chemistry is identical, so every difference below comes from the condition. 1112 CD-SR is the stronger of the two: yield strength 425 MPa (61.6 ksi) against 230 MPa (33.4 ksi) for 1112-ANN, about 85% more; tensile strength follows at 515 MPa (74.7 ksi) vs 395 MPa (57.3 ksi). In exchange, 1112-ANN is the more ductile: elongation 30% versus 13% for 1112 CD-SR, and 1112 CD-SR is harder (160 HB vs 110 HB).

1112 CD-SRChoose it when strength drives the design.
1112-ANN vs 1112 CD-SR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1112-ANN vs 1112 CD-SR — frequently asked
Is 1112 CD-SR stronger than 1112-ANN?
Yes. 1112 CD-SR has a typical yield strength of 425 MPa (61.6 ksi) against 230 MPa (33.4 ksi) for 1112-ANN — about 85% more. Tensile strength is 515 MPa (74.7 ksi) vs 395 MPa (57.3 ksi).
Which condition does FabDigit quote by default, ANN or CD-SR?
CD is the default 1112 condition in the FabDigit quote flow (neither ANN nor CD-SR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 1112-ANN or 1112 CD-SR?
1112 CD-SR. Its machinability rates excellent (87/100) against very good (78/100) for 1112-ANN.
